Blue-green algae, or cyanobacteria, in the seas are as vital to the survival of life on earth as the oxygen producing plants are on land. But marine bacteria are attacked by viruses, which can seriously affect their life-sustaining abilities. Scientists have now discovered that these viruses don’t work in the dark, according to research presented today (Monday, 04 April 2005) at the Society for General Microbiology’s 156th Meeting at Heriot-Watt University, Edinburgh.
Our earth’s breathable atmosphere relies on millions and millions of cyanobacteria in the seas absorbing the sun’s light and giving off oxygen, in exactly the same way as the photosynthetic plants and forests on land act as the other part of the planet’s lungs. The marine dwelling cyanobacteria are at the bottom of the food-web, using sunlight to produce oxygen and absorbing carbon dioxide, giving them food to grow and multiply.
But the whole delicate balance of the seas, and so the overall fate of the planet, relies on even smaller microbes called cyanophages - marine viruses that specifically attack and infect cyanobacteria. These phages can seriously damage the health of the cyanobacteria, and also the sea.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
